Same as any other, you make a toon on the server buy a guild bank thats lvl 2 (prob cost you 5k) put in 999k gold then pay $30 to xfer it to Frostmourne since its 1.7M you would need two lvl 2 guild banks and have to pay $60 since your xfering 2x guild banks to Frostmourne Alliance (assuming you want to move it to FM, you could move it to any Alliance server)
